IMPROVEMENT IN DOUBLE-ACTING SUBMERGED PUMPS.

Specification forming part of Letters Patent No. 44,89 l, dated November l, 1864 3 antedatcd October 20, 1864.

fo @Zd whom it may concern,.-

Be it known that I, ANDREW J. REYNoLDs,

` rises, a suction is produced in the lower part ot' Sturgis, county ot' St. Joseph, State ot" Michigan, have invented anew and .Improved Double-Acting Submcrged Force-Pump; and I do hereby declare that the following is a full, clear, and exact description ot' the same, reference being had to the accompanying draw ings, making a part ot' this specitication, said drawings being a vertical central section of my invention.

This invention consists in the employment or use ot' a double'acting pump cylinder, provided with two ball-valves and a tubular piston-rod, in connection with water passages, all arranged to operate as and for the purposes set forth.

To enable those skilled in the art to fully understand and construct my invention, I proceed to describe it.

Figure] is the pump. Fig. 2 is a view or plan of the same from the top of said pump.

A represents the pump-cylinder, which is provided with two ball-valves, B and C, and so arranged as to open and close the waterpassages D D alternately as the piston E rises and falls.

The operation is as follows: When piston E of cylinder A, under piston E, and valves B and O fall. The water passes into cylinder A down through the openings D D, following' piston E as it rises, while the water in the upper part of cylinder is forced up through pis.

ton E. (See red arrows.) When the piston descends, the valves B and O rise, closing the lower port D and opening the port D at the top ci' cylinder A, and the. water is then received at the top, while the water in the lower part of the same is forced up through piston E.

Thus it will be seen that I have a cheap and reliable double-acting submerged forcelpum p of an exceedingly simple construction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The cylinder A, provided with the two ballval ves B and O, in combination with the wat` rpassages D D and d, all arranged to operate in connection with a double acting hollow discharging-piston, as and for the purposes herein set forth.
